Statements that feel specific but apply to everyone create false intimacy.

Anyone try it? Did you write a sentence that felt personal but was actually universal?

Did faces react?

This Week’s Battlefield

Two Sides. Two Energy Futures.

PRO-CLIMATE

= Transition Now

= “Renewables at any cost”

PRO-DEVELOPMENT

= Pragmatic Transition

= “Don’t wreck the economy”

The Core Tension

PRO-CLIMATE PRO-DEVELOPMENT
Rapid decarbonization Gradual transition
Accept higher costs now Keep energy affordable
Government mandates Market incentives
End fossil fuels immediately Bridge fuels (gas) acceptable
Future generations Current livelihoods

This tension drives every energy policy debate.

Building Your Energy Spectacle

The Formula (Reminder)

Fact + Human Story + Stakes = Spectacle

Weak

“Solar energy costs have decreased”

Better

“Solar costs dropped 89% since 2010”

Spectacle

“In 2010, solar was for hippies. In 2025, it’s cheaper than coal. The oil companies knew — and lied.”

PRO-CLIMATE: Make It Personal

Don’t say: “Fossil fuels cause emissions.”

Say: “Every breath your child takes in Tsim Sha Tsui contains particles from coal plants 100km away. You’re paying for cheap electricity with their lungs.”

Don’t say: “We need renewable energy mandates.”

Say: “Germany did it. California did it. Hong Kong says ‘too expensive.’ Is your child’s health too expensive?”

PRO-DEVELOPMENT: Paint the Picture

Don’t say: “Energy transitions are complex.”

Say: “Ontario rushed renewables. Electricity bills doubled. Factories closed. Workers lost jobs. Is that the transition you want?”

Don’t say: “We need reliable baseload power.”

Say: “Germany spent €500 billion on renewables. When the wind doesn’t blow, they import nuclear power from France. Guess who pays? The same families who can’t afford heating.”

Scenario: Bringing It Back to Hong Kong

Renewable Energy Landscape in Hong Kong

Hong Kong’s current renewable energy usage is modest, with the government targeting 7.5% to 10% of its electricity from renewables by 2035, and 15% beyond that. This landscape includes:

Solar Energy:

  • Pros:
    • Utilizes available rooftop and building façade space.
    • Offers environmental benefits and potential cost savings.
  • Cons:
    • Requires significant rooftop space, which is limited.
    • Variable output due to weather conditions.
  • Short-term Impact:
    • Reduction in carbon emissions and potential energy savings.
  • Long-term Impact:
    • Increased energy security if grid challenges (storage and integration) are managed.

Wind Energy:

  • Pros:
    • Potential for offshore wind farms using the South China Sea.
    • Clean energy source that diversifies the energy mix.
  • Cons:
    • High installation and maintenance costs.
    • Limited land availability for onshore installations.
  • Short-term Impact:
    • Diversification of energy sources.
  • Long-term Impact:
    • Could provide a stable renewable supply if technological and cost challenges are overcome.

Waste-to-Energy:

  • Pros:
    • Addresses waste management issues.
    • Provides a steady and controllable energy source.
  • Cons:
    • High operational costs and potential public opposition due to emissions.
  • Short-term Impact:
    • Immediate benefits in waste reduction and energy generation.
  • Long-term Impact:
    • Sustainable waste management, assuming strict environmental controls are in place.

Other Renewable Options (Hydro, Geothermal, Biomass, Tidal/Wave):

  • Application:
    • Limited due to Hong Kong’s geographic constraints.
  • Impact:
    • Minimal short-term or long-term contribution compared to solar, wind, and waste-to-energy.

Places to start considering your position statement

  • Global vs. Local Perspectives:
    • How do the global case studies differ from Hong Kong’s renewable energy potential and challenges?
  • Understanding Simplified Messaging:
    • What nuances are often omitted in public messaging about renewable energy? Why might these omissions be deliberate, and what are their consequences?
  • Policy and Implementation:
    • Considering Hong Kong’s space and cost constraints, what strategies could the government adopt to enhance renewable energy integration (e.g., technological innovations, grid improvements, energy storage)?
  • Long-Term Vision:
    • How might Hong Kong’s energy landscape evolve by 2100 or 2200? What realistic pathways can be envisioned to achieve energy security and sustainability?

Activity: Energy Futures Debate

Create Your Persona

PRO-CLIMATE personas:

  • Environmentalist pushing for immediate coal phase-out
  • Parent in Tuen Mun near power station
  • Youth climate activist
  • Renewable energy startup founder

PRO-DEVELOPMENT personas:

  • CLP executive managing grid stability
  • Factory owner worried about electricity costs
  • Energy minister balancing competing demands
  • Coal worker facing job uncertainty

Who are you? What’s your story? What do you fear losing?

Human Story: The Lignite Worker

Klaus worked in German lignite mines for 30 years. His father and grandfather did too. The Energiewende shut his mine.

PRO-CLIMATE says: “Lignite is the dirtiest fuel. Closing the mines saved lives. Klaus can retrain.”

PRO-DEVELOPMENT says: “Klaus is 55. He lost his pension. His town is dying. No one hired him. He voted for the far-right. Was the transition worth it?”

The real question: How do we transition justly — fast enough to save the planet, slow enough not to destroy communities?

Remember: Fact-Check Your Stories

OK to Say

  • “Solar costs dropped 89% since 2010” (IEA data)
  • “Ontario electricity prices doubled” (Ontario Energy Board)
  • “Duck Curve creates grid challenges” (CAISO documented)

NOT OK

  • “Renewables can power everything now” (ignores intermittency)
  • “Green energy destroys economies” (exaggeration)
  • “Oil companies are literally killing people” (unverifiable as stated)

The Persuasion Playbook | Strategy #3

Sensory Hijack

People holding a warm cup of coffee rated strangers as more trustworthy than those holding iced drinks.

They had no idea the cup mattered.

The Science

This is Embodied Cognition (Williams & Bargh, 2008).

The body doesn’t just receive information — it shapes judgment.

  • Physical warmth → social warmth
  • Heaviness → seriousness
  • Roughness → difficulty

The brain takes sensory shortcuts constantly.

You Just Saw It

The arguments that landed today weren’t abstract.

They made you feel something in your body.

Not “rising temperatures cause problems.”

But: “Your grandmother’s lungs filling with smoke from a wildfire that didn’t exist 20 years ago.”
